I have a grand caravan, with a 3.8l engine.
The s-belt slipped off on my way to work, and I went to put pressure on the tensioner, and the bolt snapped in half.
I drove the van up on ramps, and was able to access the 15mm nut on the back of the tensioner. I went to O'Riley auto parts and they showed me the replacment, and then it was a snap. I used a 3/8" ratchet with the 15mm socket and two 3" extensions. It came right off, and the other one went on easily. I had a 2x2 piece of wood that I used to help hold the tensioner in place, while I worked from the back side.
You can do that by replacing the tensioner
You have to unscrew the tensioner bolt and remove the serpentine belt first, then change the pulley and replace the belt.You have to unscrew the tensioner bolt and remove the serpentine belt first, then change the pulley and replace the belt.
The belt tensioner is self-adjusting.
You can remove the old serpentine belt on your 2004 Dodge Ram by loosening the tensioner pulley. Put the new serpentine belt on and tighten it with the tensioner pulley.
Fit a new belt tensioner
The fan is electric, not belt driven. The serpentine belt is has a spring loaded tensioner. If the belt is loose, the tensioner has failed.
What you need is a ratchet 15mm socket. Losen the idler then slide off the serpentine belt off. There should be a diagram for routing the belt if not draw a diagram before removing it. Replace the serpentine belt crank it 2 or 3 times but don't start the engine. The 4th time start the engine this time the as the engine is idling eyeball the belt agaisnt the tensioner idler and crank pulley make sure the serpentine is algined. A Note: Make sure that you have identified the tensioner pulley as apposed to the idler pulley. With the 15mm socket on the tensioner pulley's bolt, rotate it clockwise and this will release the tension on the belt, or in the case of installing a new serpentine belt, allow you to get it where it belongs. This is the case on my 1997 Dodge Caravan, and probably other year makes. Best of luck- Bryan 1993 Dodge Grand Caravan: Rotating the tensioner pulley's bolt clockwise was the way to replace my belt. By the way, the tensioner pulley in my van was one of the smaller ones in the middle of the whole system, attached to a silver arm coming off the tensioner. Good luck...

15/32 wrech on tensioner at water pump pully pull towards you will releave tension replace fopllowing diagram lots of muscle recomend cheater bar
The belt tensioner is rotated clock wise with a 15 mm wrench or belt tool.
Yes, on a 3.3 or 3.8 the serpentine belt pulley does come off the tensioner arm but the bolt is left thread not right handed.
The serpentine belt on a 2003 Dodge Dakota is replaced by loosening the belt tensioner and slipping the belt off. It can then be removed from the engine accessories and a new belt installed.
